Yam khoom twg zoo dua rau kev kub siab resistant O-rings?
fluororubber
Thaum xaiv cov khoom siv rau kev kub siab O-rings, fluoroelastomer (FKM) feem ntau suav hais tias yog qhov kev xaiv zoo dua. Fluorine roj hmab muaj npe nrov rau nws cov tshuaj tiv thaiv zoo heev, tiv thaiv tshav kub thiab roj tsis kam, thiab tsim nyog rau kev sib khi yuav tsum nyob rau hauv ib puag ncig hnyav xws li kub, kub siab thiab kub ceev. Nws muaj cov cuab yeej zoo thiab ua haujlwm rau ozone, kev laus thiab huab cua, ua rau nws tsim nyog rau kev siv siab.
Txawm hais tias lwm cov ntaub ntawv xws li nitrile roj hmab (NBR) kuj muaj cov roj zoo, lawv tuaj yeem ua kom tawv lossis muaj hnub nyoog nyob rau hauv qhov kub thiab txias. Txawm hais tias hydrogenated nitrile roj hmab (H-NBR) tau txhim kho kev tiv thaiv tshav kub thiab tiv thaiv ozone, kev laus thiab huab cua, nws tseem tsis tau tiv taus qhov kub thiab txias li fluororubber. Txawm hais tias ethylene propylene diene roj hmab (EPDM) muaj ozone zoo heev thiab dej kub tsis kam, nws qhov kub thiab txias thiab roj kuj tsis zoo li fluororubber. Txawm hais tias silicone roj hmab (SI/VMQ) muaj kev tu cev zoo thiab ua rau cov kab mob loj hlob, nws tsis yog kub-thiab roj-resistant li fluororubber.
Yog li ntawd, coj mus rau hauv tus account siab tsis kam, tshuaj corrosion kuj thiab tshav kub kuj, fluorine roj hmab (FKM) yog ib tug zoo xaiv.
